1、Designation: E3074/E3074M 16Standard Practice forClearance Examinations Following Lead Hazard ReductionActivities in Single Family Dwellings, in Individual Units ofMultifamily Dwellings, and in Other Child-OccupiedFacilities1This standard is issued under the fixed designation E3074/E3074M; the numbe

2、r immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.

3、1 This practice covers visual assessment for the presenceof deteriorated paint, surface dust, painted debris, and paintchips with environmental sampling of surface dust to deter-mine whether a lead hazard exists at the time of samplecollection, following lead-hazard reduction activities, or otherbui

4、lding maintenance and modification activities.1.2 This practice addresses clearance examination of single-family detached dwellings (including exterior structures, suchas fences), individual units in multifamily dwellings, commonareas or exterior sites, and child-occupied facilities.1.3 This practic

5、e also addresses clearance examinations thatmay include soil sampling, for example when soil abatementhas been performed.1.4 This practice includes a procedure for determiningwhether regulatory requirements for lead clearance levels fordust and, where warranted, soil have been met, and, conse-quentl

6、y whether a clearance area, passes or fails a clearanceexamination.NOTE 1This practice is based on that portion of “clearance” describedfor the United States of America in 40 CFR Part 745 for abatement, andin 24 CFR Part 35 for lead-hazard reduction activities other thanabatement.1.5 The values stat

7、ed in either SI units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.6 Th

8、is standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

17、med with the idea ofdetermining if the space undergoing the evaluation is safe forreoccupancy.3.2.2 clearance area, nwork area and additional spacesoutside the work area where lead contamination may haveoccurred during lead hazard reduction and other buildingmaintenance or modification activities.3.

18、2.2.1 DiscussionThe spaces outside the work area mayinclude rooms connected to the work area, egress routes, wastestorage areas, and grounds adjoining exterior work areas.3.2.3 clearance examination, nthe process of conductinga combined visual and quantitative environmental evaluationused to determi
